//
// To generate signatures for the LmUtility native methods:
//
// 1. Build the Language Manager. This will create
//    w:/lib/nt/debug/mxlangman.jar.
//
// 2. Run the following commands:
//
//    cd w:/langman
//    javah -jni -classpath w:/lib/nt/debug/mxlangman.jar \
//          org.trafodion.sql.udr.LmUtility
//
// 3. Copy signatures from the newly generated file
//    org_trafodion_sql_udr_LmUtility.h into this file.
//

// NOTE: The native methods declared in this file have to be
// ----  registered with the appropriate Java class by calling 
//       the 'RegisterNatives()' JNI method. Currently the 
//       following methods are available to register the native
//       methods.
//       
//       - registerLmUtilityMethods() 
//         Registers native methods of LmUtility Java class
//
//       - registerLmSQLMXDriverMethods()
//         Registers native methods of LmSQLMXDriver Java class
//
